WALTER 11. WHE LER, an, or STAMFORD, connnc'rlour, ASSIGNOR ,ro PITNEY-BOWES POSTAGE 1VIETER1CO.,0F STAMFORD, connnc'rrou'r, A CORPORATION on DELAWARE ROTARY HAND CANGELER Application filed. April 5, 1932. Serial No. 603,361.

This invention is a novel improvement in rotary hand cancelers or printers particularly adapted for the cancellation of mail in post ofiices; but may be used in any device for making an impression by means of a.

rotary or oscillating die.

7 Heretofore, rotary hand cancelers or stamps have been made in one piece with an inking mechanism mounted therein in such a 10 manner as to render same diflicult or slow to remove; orso constructed that it is diflicult to prevent the hands of the operator becoming smeared with ink; or so constructed that it has been necessary to remove screws or 1 thumb nuts when removing the inking mechanism which screws may become lost. Same have also been made in two parts, the die and main casing in one part; and the handle, base, and inker in the other; and in such construc- 29 tion the die section is removed and the device inked'by rolling the inking section in the ink while holding the handle in the hand. But when a device of such two-part construction has been used for a time, the separable die section develops play at the point where it is separably fastened to the handle section. Toggles, clips, crowned thumb nuts, and other means have heretofore been used as a fastening means, but without obviating the difliculties arising from the development of this play. a

The principal object of my invention is to provide an inexpensive readily removable bracket carrying the inking roller which bracket may be held in the canceler frame by a single flat or bow spring, whereby the bracket carrying the inking roller may be readily snapped out of the frame, re-inked, and then snapped back again into position in the frame with a minimum loss of time, there being no parts which might become out of adjustment or which might be lost.

A further object is to provide a hand canceler in which the die and handle are carried by the main frame and the inking roller by a sub-frame, whereby the inking roller may be re-inked rapidly and easily without smearing ink on the handsof the operator, and without removing any parts except the inking subframe itself, same being accomplishedwithenable others, familiar with the art, to adopt and use the same; and will summarize in the claims the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawing:

Fig. l'is anendelevation of my rotary hand canceler.

Fig. 2 is a vertical section therethrough.

As shown in thedrawing, my rotary hand canceler or stamp consists of a U-shaped frame 1, in the upper open end of which is rotatably mounted a printing, or canceling die 2 journaled on a spindle bolt 1a extend "ing between the legs of the frame. A socket 3 is welded to thebase of frame 1, and a handle 4 of wood or other suitable material is forced into the socket 3 andsecurcd therein by pins 4a.

A U-shaped sub-frame 5 is removably and pivotally mounted between the legs of frame 1, said sub-frame carrying pins 6 which are riveted or otherwise secured to the sides of the sub-frame 5, and engage open bearing.

slots 15 in the legs of the frame 1. The two pins 6 which are riveted to the inking subframe 5 have shoulders 6a to locate the assembly in the slots 1?) of frame. 1, and have cupped heads 6?) to afford a good grip for the.

fingers of the operator. In the sub-frame 5 is rotatably mounted an inking roller 10 of felt or the like ournaled on a removable spindle bolt 11 held in place by a shouldered screw 11a. I The inking sub-frame 5 is made in the form of a boxer hood so that when removed from frame '1 and when rolling the roller10 in the ink the operator can hold the cupped oted around a pin 8 in the frame 1, the lower le of the s )rin bein Jrevented from swin b b g b ing in the frame when the inking sub-frame 5 is removed by a pm 9.

The contact points of the ink roller 10, die

2, slots 1?) and theposition of the pins 6, and the shape of the bow spring 7 are such that the spring 7 will hold the sub-frame 5 firmly in place with the ink roller 10 pressed against the die. To remove the sub-frame, the pins 6 are grasped between the thumb and finger and pulled out. To insert the sub-frame, the pins 6 are grasped as above, and the inker snapped in place by pushing the curved base plate 5a of the sub-frame 5 over the end 7a of the spring 7and by pushing the recessed portions of the pins 6 into the slots 12 The free end 7a of spring 7 may be grasped with the thumb While the handle is held in the hand, and pulled downward toward the handle, as an aid in inserting the sub-frame; but it may be inserted very easily by simply forcing the spring 7a downward by means of. the curved base 564 of the sub-frame 5 asthe roller 10 rolls over the die 2 in the act of directing the sub-frame between the spring 7' and the die 2.

I/Vhen the ink roller Wears out, a new one may. be inserted by removing the inker. .rom the device as above, and removing the screw 110; and the spindle 11.

I claim:

1. In a rotary printing device, a frame, a rotary printing die carried by the frame, a removable sub-frame pivotally supported in the frame, an inking device carried by the sub-frame, and common means for yieldably retaining the sub-frame in said frame and for pressing the inking device against the die.

2. In a rotary printing device, a frame, a rotary printing die carried by the frame, a removable sub-frame pivotally supported in the frame, inking devices carried by the subframe, and means for normally retaining the sub-frame in said frame with the inking devices engaging the die; one of the frames carrying pins engaging open slots in the other frame.

3. In a rotary printing device, a frame, a rotary printing die carried by the frame, a removable sub-frame pivotally supported in open slots in the frame, inking devices carried by the sub-frame, and means for nor-- mally retaining the sub-frame in said slots and for pressing the inking devices against the die.

4. In a device as set forth in claim 3, said frame being U-shaped and said printing die being journaled in bearings adjacent the outer ends of the legs; and a handle secured to the base of the frame.

5. In a rotary printing device, a frame, a rotary printing die supported therein; a removable sub-frame; an inking roller mounted in the sub-frame, pins on the sub-frame; open slots in-the frame receiving said pins; and a spring in the frame engaging the subframe for normally retaining the pins in the slots and for pressing the inking roller against the die.

6. In a device as set forth in claim 5, said frame being U-shaped, and said printing die being journaled in bearings adjacent the outer ends of the legs; and a handle secured to the base of the frame.

9. In a device as set forth in claim 5, said spring beingbowed with one end fixed to the frameand the other end engaging the subframe, and yieldably pivoting the sub-frame towards the die.

10.. In a rotary hand printing. device, a U-shaped frame, a rotary printing die journa-led therein; a U-shaped sub-frame removably and .pivotally mounted in the frame; an inking roller journaled in the sub-frame; aligned pins on the legs of the sub-frame; op posed open slots in the legs of the frame receiving said pins; and a bow spring in the base of the. frame engaging the base of the sub-frame for normally retaining the pins in the slots and for pressing the inking roller against the die. 7

11. In a device as set forth in claim 10, a handle secured to the base of the frame.
